Training effect on sex-based differences in components of the Shepard and Metzler mental rotation task.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSpatial ability has been reported to indicate sex-based differences in humans, mainly assessed by Shepard and Metzler mental rotation task (SM-MRT). Most performances in earlier studies have been evaluated by the mean value of reaction time and/or accuracy. The performance indexes might not be sensitive measures of mental rotation. Sex-based differences in the performance might also be involved in the spatial experience of the subject at the time. This study observed variations in components of the SM-MRT over repetition.
methodsMale (n = 17) and female (n = 17) subjects completed 20 days of repeating the SM-MRT. The slope and intercept of the function performance (reaction time) to the angular disparity are calculated; the slope of this function indexes the mental rotation (main-process), and the intercept indexes the other sub-processes.
resultsA significant main effect of sex was obtained on the slope. The intercept also showed a tendency toward statistical difference. The interactions between the sexes and the day were not significant for the indices. Statistical testing for coefficient of variations (CV) indicated no sex-based difference in the effect of the intercept throughout the experiment day. The CV of the slope, however, showed tendencies toward sex-based difference from days 7 to 12.
conclusionsThe difference between the sexes in performance on the slope was sustained throughout the experimental period. A few female subjects who demonstrated larger slope values than male subjects caused the sex difference. The learning rate of mental rotation may be an inherent spatial ability.
